MACHINE FOR HARDENING HATS.

Application filed December 23, 1919.

To all whom it may concern:

lie it known that we, MICHA L KRAJNAH and JOHN MADUNIGKY, citizens of the Czecho-Slovakia, residing at avenue, Danbury, (2) 459 North Main St, Danbury, county of Fairfield, State of Connecticut, have invented an Improvement in Machines for Hardening Hats, of which the following is a specification.

The object of the present invention is to harden the felt of bat bodies. The unshaped bodies are dipped in water and are then piled in stacks, preferably twelve bodies to a stack, in flatwise fashion. A stack is then rolled up in burlap or other suitable material, and placed in our novel machine and rolled therein to harden the felt.

l/Vith this object in view, the invention comprises the novel construction, arrangement and combination of parts as hereinafter fully described and clearly shown in the accompanying drawing.

In the drawing,

Figure 1 is a side elevation of the device;

and Fig. 2 IS a Vertical longitudinal section thereof.

The frame consists of up'rigffti3il, 12 and 13 at opposite sides thereof, horizontal braces 14 and 15 for the uprights, and upper and lower cross connecting members 16, 17 and 18. Carried on the frame is an obliquely arranged bar 19 having a hook 20 at its up: permost end. Also on the frame are the obliquely arranged braces 21. Plvoted to brackets 22 on these braces is a table 23 of sufficient size to accomplish its purpose, and having attached to it the bearing blocks 24 for a shaft 25 which extends across the ma chine and the ends of which are mounted in the brackets 22. \Vhen in horizontal position a portion of the lower surface of the front half ofthe table rests on upper cross connecting member 18. Secured to opposite braces 15 and between the uprights 11 and 12, are bearing blocks 26 which have journaled therein a crank shaft 27 carrying a belt pulley 28. Two oblique bars 29 are each pivotally mounted at their lower ends on the crank shaft adjacent the outer sides of the bearing blocks 26. At suitable points the oblique bars 29 are provided with rectangular openings 30 in which are blocks 31 arranged to reciprocate therein. The slides are held in the slots in any convenient manner, as by a tongue and groove connection.

Specification of Letters Patent.

1) 7 'Maple Patented J nne 15, 1920. Serial No. 346,877.

Thecrank shaft 27 carries a crank arm 32 to which is pivoted by means of bearing blocks 33 a plate 34 width with the table. Near its upper end and adjacent its side edges, the plate 34 carries bearing blocks 35 for a shaft 37 journaled'in sliding blocks 31.

The oblique bars 29 have screw eyes 38 adjacent their upper ends, and to the screw eyes are attached ropes 39 which travel over guide pulleys 40 on the frame and have attached thereto weights 41 to counterbalance the oblique bars. The upper ends of the oblique bars are connected by a cross piece 42, which has attached thereto intermediate its ends a chain 43 any of the links of which may be engaged with hook 20 to regulate the pressure upon the bundle of hat bodies. The opposite uprights 13 at the front of the frame have pivotally attached to their outer sides as shown at 45 the toggles 46 each having an upper arm 47 and a lower arm 48 pivoted together at 49. The upper arms are each pivotally attachet to the brackets 50 which are shown, to oblique bars 29. Arranged at the front of the machine and carried by the front ends of the arms 48 of the toggles is a treadle 51.

Table 23 has attached to it near its rear end and adjacent its side edges, ropes 52 which pass over guide pulleys 53 on theupsecured, as

per arms of the toggles and the other ends of which are attached to the treadle. The table is counterbalanced by means of weights 54 suspended from the rear edge thereof.

The apron is indicated as a whole by 55. It comprises ropes 56 and round rods 57, shown as threaded thereon, which lie in parallel relation to each other, the element as a whole'being thoroughly flexible. This apron is of sufficient width and length to'eifectually roll the bundles of hat bodies therein. The ends ofthe ropes are attached, respectively, to table 23 and plate 34, near the front edges thereof, and in working position the apron partly infolds the bundle of hat bodies and rolls it as the plate 34 reciprocates and oscillates as hereinafter described. As'shown, the lower portion of the apron rests on the table, and the upper portion thereof is stretched taut by its connection with plate 34. A guard 58 at the front of the machine prevents the accidental dropping of the bundles of hatbodies as they are placed in or removed from the apron.

l at their upper ends.

which corresponds in to their normal positions,

In operation, the foot applied to the treadle opens the toggles and gives a downward pull on ropes 52, thereby forcing plate drop to the lowermost the chain 48, weights as heretofore mentioned, to regulate the pressure on the bundle of hat bodies, are

made by passing any desired link over the hook 20.

Power is now applied to pulley 28 to revolve the crank shaft and its crank. As

will readily be understood, a combined recip- I willimpart the desired the apron.

rocatory and oscillatory motion is thereby imparted to plate 34%, and the sliding blocks are caused to reciprocate in the openings in the oblique bars. The weight of the oblique bars and plate, 'as adjusted by means of chain 43, will keep the oblique bars in their working position, and the combined reciprocatory and oscillatory movement of the plate rolling movement to After the machine has been started its operation may be continuous. W hen a bundle of bat bodies has been sufficiently treated, the operator by pressure on the treadle, opens the toggles which places the plate,

apron and table in the position shown in Fig. 2. As soon as the hardened bundle of hat bodies has been removed and anew one placed on the apron, the operator removes his foot from the treadle and the operation proceeds as before. 7
